BACKGROUND OF INVENTION This is a continuation-in-part of co-pendingapplication Ser. No. 767,212 filed Oct. 14, 1968, now abandoned.

This invention relates to a replaceable spike for shoes. In particular,it relates to replaceable spikes for use on athletic shoes such as golfshoes and the like.

Although there have been a number of replaceable shoe spikeconstructions described in the past, such constructions generally haveone or more disadvantages. Thus, Langer, US. 2,607,134 described areplaceable spike which is diflicult to remove without causing damage tothe shoe. Further, its construction is subject to snapping withcontinued flexing of the sole of the shoe.

Threaded spike constructions have also been described, as for example,in US. Patents 2,895,235; 2,689,417; 2,582,053; 2,578,591; 1,435,872;1,025,087; 325,194 and 19,205. The spikes of these patents similarly arediflicult to replace or have holders of insuflicient strength.

Other patents dealing with replaceable spikes have been found to begenerally costly and complex.

One object of the present invention is to provide a replaceable spikeconstruction which is sturdy, simple and inexpensive.

A further object of this invention is to provide such a constructionwherein the spike is easily inserted or removed.

Further objects and advantages of this invention will be apparent fromthe description and claims which follow taken together with the appendeddrawings.

SUMMARY OF INVENTION The invention comprises two cooperating components.One is either a two-piece anchor comprising a retainer member and areceiving chamber having a solid rim engageable with the inner surfaceof the outer sole and a depending interiorly threaded tubular portionextending through the sole or a one piece version bent over onto awasher.

The retainer member has a tubular portion with exterior threadingengageable with the interior threading of the receiving chamber and arim or flange engageable 3,566,489 Patented Mar. 2, 1971 with the outersurface of the outer sole. The retainer member is characterized ashaving in the extreme portion of its tubular section a recessed orchamfer portion so that the end of the retainer tubular section adjacentthe inner sole has a larger interior diameter than the body of thetubular section.

The second component is a replaceable spike member. This membercomprises an exterior spike portion, a median seating flange, and alocking portion terminating in split fingers having protuberances attheir ends. The median flange is preferably chamfered to seat in amating chamfer of the retainer member. The locking portion is pushedthrough the tubular portion until its split finger protuberances engagethe inner chamfered area of the retainer member.

The receiving chamber is forced in from the interior of the shoe. Theretainer member is threaded into the receiving chamber by a simple toolengageable with orifices provided in the rim of the retainer member. Thereplaceable spike member is locked into the retainer member by simplepressure. Removal of the spike member is accomplished by inserting awedge-like tool between spike member flange and retainer member rim. Itis preferable to use a tool which applies wedge action on opposite sidesof the flange and rim joint. Such a tool comprises a narrow short wedgeend having a slot so as to operate on both sides of the rim-flangejoint.

In the one-piece anchor version, there is a tubular member having aflange on the outer surface of the outer sole and having a portion bentover onto a washer on the inner surface of the outer sole.

Although the replaceable spike member of this invention is easilyinserted or withdrawn by the use of an appropriate tool, it remainsfirmly in place during even the most violent flexing of the shoe sole.Further, even if the receiving chamber should loosen and turn because ofimmersion in water or mud, the spike will nevertheless stay in place.

The components of this invention are relatively simple and inexpensiveto fabricate. Further, the strength of the spike is at least equal andin many cases superior to the strength of commercially available spikesfor athletic shoes and the like.

SPECIFIC EXAMPLES OF INVENTION Referring now to FIGS. 1-4 of thedrawings, the receiving chamber 30 is inserted below the inner sole 32so that its solid rim 30a engages the inner surface of the outer sole 31and its depending tubular portion 30b with interior threading 30cextends through the outer sole 31 to its outer surface.

The retainer member 11 has an annular rim 11a adapted to abut the outersurface of the outer sole 31. Retainer member 11 has a tubular portion15 which is open at the bottom and has an upper chamfer recess 17 and alower chamfer 19. The retainer member 11 with its exterior threading 11bis adapted to be threaded into the tubular section 30b. Orifices 21 areprovided so that an appropriate tool may be inserted to assist inthreading the retainer member 11 tightly into place. When retainermember 11 is tightly in place, the rim 11a abuts the outer sole 31 andthe tubular section 15 abuts the solid rim 30a.

The replaceable spike member 10 comprises an exterior spike portion 10a,a median seating flange 20 with a chamfer 22 and a locking portion 14terminating in a pair of split fingers 12 having terminal protuberances16 and 24. The replaceable spike member 10 is adapted to have itselongated locking portion 14 extend through the tubular section of theretaining member until the protuberances 16 and 24 are seated in therecess 17. The member 10 is so proportioned that the median flange 20will seat with its chamfer 22 against chamfer 19 when the protuberances3 are locked into the recess. The diameter of the base of the lockingportion is such as to give a fairly close fit in the tubular portion ofthe retainer member.

Insertion of the replaceable spike member is done by simple directpressure. Removal is accomplished by applying wedge pressure between therim 11a of the re: tainer member and the flange of the replaceable spikemember. A preferred tool is illustrated having a narrow wedge end splitby a notch 41 so that both sides of the wedge 42 will fit around thebase of the elongated locking member 14.

In the one-piece anchor construction illustrated in FIGS. 5 and 6, theanchor member 111 comprises an outer flange portion 111d, a tubularportion 111c having an inner recess 111b with an extension 111a bentover the Washer 130 onto the inner surface of an outer sole 131 below aninner sole 132. There are thus two cavities in the anchor 111, namely anarrow entering cavity 111 and a wider seating cavity 111e. Thus, whenreplaceable spike member is pushed into the cavities 111 and 111e, itssplit fingers 112 permit the protuberances 116 and 124 of the lockingportion 114 to pass through cavity 111 and then lock into cavity 111e.The protuberance 120 seats tightly against the flange 111d.

I claim:

1. In combination:

(a) an anchor comprising a rim adapted to engage the inner surface of ashoe sole and a tubular portion adapted to extend through such sole andterminate in an annular rim abutting the outer surface of the shoe sole;said tubular portion being open at the bottom and having a recess in itsupper inner portion; and

(b) a replaceable spike member comprising an exterior spike portion, amedian seating flange adapted to abut said annular rim and an elongatedlocking portion adapted to extend through said tubular portion andhaving longitudinal split fingers with terminal protuberances adapted tobe seated in said recess.

2. Claim 1 wherein said anchor comprises in cooperable combination:

(a) a receiving chamber having a tubular portion adapted to extendthrough such sole and having interior threading; and

(b) a retainer member comprising a tubular portion open at the bottomand having exterior threading adapted to engage the interior threadingof said receiving chamber; the upper inner portion of said tubularportion having the recess.

3. Claim 1 wherein said annular rim and spike member flange haveregisterable chamfers.

4. Claim 1 wherein said annular rim has an orifice for engagement by atool.
